WINDOW-SCREEN.

' Patent and catches behind the' flange thereof. In

Be it known that I, JACOB S. SPEER, of order to i s rt the window screenframe Springfield, county of Green, and State of Missouri, have inventeda certain new and useful Window-Screen; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, in which like letters refer tolike parts.

The object of this invention isto improve the construction of windowscreens and the like to render the same simple, durable and easy tomanipulate and mount. The frame of said screen is of sheet-metal and theother so that there is no wood, and when the metal parts are madenon-corro- I sive, the window screen is sanitary and ex- The t re of theInvention will be undertremely durable, as no part thereof can de- Stoodm h a co panymgdrawmgs and cay, and it also presents an attractive aphefollowmg description and clauns. penance, In-the drawin Figure 1 1s afront eleva- The chief feature of the invention con- 1 11 ofthe Wm owscreen.

Theframe, wire fabric, binding rod and oval disks are all entirely separatefrom each other until assembled and then merely frictionally engage eachother,'so that there are no screws, nails, springs or similarobjectionable fastenings.

Another feature of theinvention consists in the means for mounting thiswire screen. An arm is secured to the side of the window casing so as toproject over the channeled sides of the window screen frame wheninserted in the window casing, and a lever is pivoted to the projectingend of each arm with a. head turned U-shaped substantially dow screenframe is cut away at suitable polnts. releasable fastener is providedfor securing the lower end of the window such operationthewindow screenwill reig. 6 is a perspect' the metal strip for forming the frame outready to be bent into position, and the bent position being indicated bydotted window casing, the upper portion of the window casing beingbroken away. Fig. 8 is a section on the line 8-8 of Fi 7, the screenbeing shown pushed outward y at the lower end by the dotted lines. Fig.9 is an enlarged view of what is shown in the upper part of Fig. 8. Fig.lOis a horizontal section on the line 10-10 of Fig. 9. Fig. 11 is asection on the line 11-11. of Fig. 8. Fig. 12 is a section on the line12-12-0f Fig. 11. 7 The window. screen. is provided-with a frame 10 madepreferably of a strip of sheet metal formed with a-narrow. flange 11 onone side and a wider: flan e12. op'osite thereto on the other ed e, t etwo anges opposing each other an therefore projecting in the samedirection relative to the body of the strip. This leaves between'the two11 is turne thereof. The narrow flan so that the extreme end of the headpr0 ects strip. The wide flange 12 is shaped like into the channel ofthe window screen frame molding on the outside, and therefore has aoversaid levers, the inner flange of the win-- per left-hand corner partsbeing broken 'ort-ion of the top of the window screen..

Fig. 7 is a front elevation of the screen in a,

flanges a channel extending. longitudinallg beyond a right angle to tebody of the;

screen to the window casing. With this'conpractical;

I main suspended at its upper ends from said ve view of a portion oflongitudinal groove formed by it and the I the frame with its edgeslying upon the wide flange 12 and over the groove between it and thebody' of the strip. Then the rods 17 are laid upon the edges of the wirefabric, one on each of the four sides. Oval disks 18 are laced in thechannel and they are provide with rectangular holes 19 for the insertionof a tool or wrench for turning same and are made of such dimensionsthat the narrow diameter is less than the space between the rod 17 andthe flange 11 of the frame, while the greater diameter is slightly inexcess of said distance, so that the disk can readily be inserted andturned and wedged ti htly in the channel between the rod 17 an theflange .11 of the frame. In order to strengthen the hold of said disks,they are beveled on the periphery, the wider side of the disks beingplaced against the body of the frame, and since the flange 1'1 overhangssomewhat, they will not escape from said flange nor from the rod, asthey tend to press the rod outwardly somewhat against the flange 12 andwedge in between said rod and the body of the frame. There fore, theessential part of the window screen I consists of the channeled frame,the wire fabric, the rods 17 and the disks, all independent of eachother before amemblage and each made of metal, and the parts may beeasily assembled and as easily separated. This makes the window screenvery simple and durable, especially when the metal parts are madenon-corroslve as they should be. And the window screen, as a whole, issuperior to the ordinary wooden framed screens.

On one end there is a cover plate 21 adapted to close the space betweenthe top of the window screen and the window sash. It has in ittransverse slots 22 for screws 23 which extend from the frame 10,whereby the plate 21 is adjustably secured in place to accommodateitself into a particular window casm 25 1s a window casing and on eachside an I arm 26 is secured that projects outwardly at an upwardlyinclined angle to point in front of the channel of the frame. On theouter end of said arm a lever 27 is pivoted between its ends, one endbeing relatively long to be manipulated and the other end formed into ahead that is first bent at a right angle from the body of the lever soas to project into the channel of the window screen when in place,

see Fig.- 10 and the extreme end of the head is turned laterally so asto project behind the flange 11 of the window screen frame when inplace. This makes the head of the lever substantially U-shaped. Theflange 11 of the window screen frame is cut away at 28 so that saidframe may be placed over the heads of said levers in Inserting thewindow screen into the casing. Then the window screen frame is loweredsomewhat to the limit, said holding devices bein located at the upperend thereof and the levers actuated so that the heads thereof firmlybind the frame of the window screen frame against the window casing andhold the same tightly in place.

The lower end of the window screen frame is held in position by thecatch lever 30 which is pivoted to the lower part of the window casing.by the pin 31 and has one end lengthened for manipulation and on theother end there is a laterally bent head 32 adapted to enter the channelof the frame of the window screen and bind the flange 11 thereof againstthe window casing.

For letting flies or dust out, the lower fastening may be disengaged andthe lower part of the wlndow screen pushed outwardly. During thatoperation the window screen will be suspended from the heads of thelevers 27 above. The window screen can be then pushed back and fastenedon the lower fastener.

What I claim as my invention and desire to secure by Letters Patent is:

1 A window screen including a frame provided with two longitudinally.extending opposing flanges with a channel between them, a abric with theedges thereof extending into said channel against oneof said flanges, arod, in and extending longitudinally of said channel and resting uponthe fabric, and means in said channel adapted to wedge between said rodand the opposing flange of said frame for securing the fabric to saidframe.
